TUFTING-BUTTON.

SPECIFICATION forming part of Letters Patent No. 767,885, dated August 16, 1904.

Application filed December 26, 1903. Serial No. 186,744. (No model.)

To all whom it may concern:

Be it known that I, HENRY HIGGIN, a citizen of the United States, residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Tufting-Buttons, of which the following is a specification.

The object of my invention is to provide a tufting-button of improved construction; and my invention consists in the combination and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a tufting-button embodying my invention; Fig. 2, a longitudinal section of the same, and Fig. 3 a longitudinal section through the head of the button at right angles to Fig. 2.

The clenching-tangs A are provided with head-flanges B, which are joined to the tangs by means of bases C. The bases C are concave in cross-section, with the concavity in each base facing that in the other and decreasing in both depth and width from the button-head to the juncture with the body of the tang. A head-cap D is clenched over head-flanges B to form the button-head and to cause the tangs to lie closely adjacent to each other, as shown. The concave bases of the tangs prevent cutting and tearing of the covering of the cushion and cause the tangs tobend at a line a some distance from the button-head.

In the process of manufacture, especially where the button-heads are covered with cloth or the like, considerable pressure is exerted on the head-flanges B, tending to bend them out of their true relation with tangs A, and thus interfere with the proper assembling of the parts. In such cases it has been found necessary to make special provision against bending. Owing to the fact that the juncture of bases C with head-flanges B is in the form of a curve extending back from the edge of the flange, the bending-line of the flange is fixed to pass through the solid body of the flange at a position which has not been weakened by previous bending, so that the full strength of the material in the head-flange is utilized to prevent bending thereof during the process of manufacture, and no special provision against bending is required.

I claim as my invention 1. A tufting-button having fiat clenchingtangs joined to the button-head by bases which are concave in cross-section, said concavity being full at the juncture and merging into the tang a short distance from the head, substantially as specified.

2. A tufting-button having flat clenchingtangs provided with head-flanges adapted to be engaged by a head-cap to form the buttonhead, the juncture between said tangs and head-flanges being through the medium of bases which are concave in cross-section, said concavity being full at the juncture and merging' into the tang a short distance from the head, substantially as specified.

3. Atufting-button having clenching-tangs adapted to lie closely adjacent to each other and provided with head-flanges adapted to be engaged by a head-cap to form the buttonhead, the juncture between said tangs and head-flanges being through the medium of bases which are concave in cross-section with the concavity in each base facing that in the other, said concavity decreasing both in depth and width from the button-head to its juncture with the flat portion of the clenchingtangs, substantially as specified.
